I wonder which barrels folks would choose - chrome, nitrate, or other if they knew it was going to be on a dedicated M16 which will see a good amount of full-auto and/or 3-burst fire? I'm not aware of anything better than chrome, but I really haven't researched this in a long time either.
For most shooters, Nitride is probably best. But like you noted, chrome is more appropriate for military use and with full-auto firing and extreme duty cycles. Even if I was firing full auto, I'd still go with Nitrade for better accuracy and increased corrosion protection.
